What gauge or gauges are you talking about? What year are t he gauges and what year is your Opti? If I recall correctly, the gauges changed in 2001 or 2002. Not sure of the exact date. I have a 115 Opti and bought the System Monitor 1000. They also have tach and speedo digital gauges. I installed the System Monitor myself but all I had was a data cable to connect in a CAN (Control Area Network)setup.
I don't have any wires to speak of, just a connector similar to what you might find on your pc. Just with different pinouts and the actual connector.
I got my wiring diagram out of my Mercury Service Manual. Well worth the cost by the way. If I can find my extra copy of the diagrams, I could send them to you.

P.S. You can reply here but it would probably be best to email me directly also so I will get it. I'm not browsing this site as often anymore...
